MACHINE FOR FORMING WIRE BAlLS.

SPECIFICATION forming part of Letters Patent No. 520,864, dated June 5,1894.

Application filed April 4, 1892. Serial No. 427,716. (No model.)

To all whom it may concern:

Be it known that I, HENRY S. REYNOLDS, a citizen of the United States,and a resident of Brooklyn, in'the county of Kings and State of NewYork,have invented certain new and useful Improvements in Machines forForming the Ends of Wire Bails, of which the follow ing is aspecification.

My invention relates to certain improved machinery for forming thecircular ends of Wire bails for vessels, such as pots, pails and thelike, and has for its object the formation of such circular endsrapidly, accurately and economically.

To this end my invention consists in the especial mechanism hereinaftermore fully and particularly described and pointed out in the claims.

Referring to the drawings, in the several figures of which like partsare similarly designated, Figure 1 is a side elevation of the tool. Fig.2 is a front elevation. Fig. 3 is a top plan view of the base-plate andits attachment. Fig. 4 is a bottom plan View of the plunger or former,and Fig. 5 is a portion of a bail having a circular end ready to be 7secured in the ears of a vessel, formed in accordance with my invention.

1 is the base plate having rigidly mounted thereon the mandrel 2, thewire guide 3, and the adjustable wire gage 4:. The mandrel 2 consists ofan upright pillar or post having at its top the reduced circular portion5. The wire guide is provided with a slot 6, of considerably greaterwidth than the size of wire forming the bail.

said hollow or recess 10, spirally cut away, as

at 18, the inner side 14 of said wall describing a greater curve thanthe outer wall thus producing a general screw action upon the descent ofthe tool. The opposite wall 15 of said tool is more or less cam-shaped,as shown, having at the inner side and near the top On the mandrel sideof' the guide proper, and in line with the diam-- thereof the cut-awaybend, are or chamfer 16 (Fig. 1). These walls 13 and 15 do not join atthe top but are separated by the horizontal integral ring-shaped portion17, provided with a slot or recess 18, which, on the full stroke is inline with the slot 6, in the wire guide 3, affording a passage-way forthe unmanipu- I lated wire of the bail.

The operation of my device is as follows:- The wire for the bail beingfirst out off to the required length, one end is introduced through slot6 in guide 3 and inserted past the circular portion 5 of mandrel 2,opposite to the shoulder 7, until it strikes the adjustable gage 4. Thedrop is then sprung and the end of the wire is engaged by the spirallycut wall 13 of tool 9, and twisted about the circular extension 5 of themandrel, producing the inner curve 19 of the wire, and, upon the furtherdescent of the tool, the opposite camshaped wall 15 of said toolprovided with the bend, are or chamfer 16, produces the outer curve 20on the bail, (Fig. 5,) the unmanipulated portion of the wire extendingthrough slot 18 of the tool and through the slot'6 of the guide. The adjustment of the gage 4 is such that the wire at the end of the bail doesnot describe a complete circle, but is left with the opening 21 (Fig.5), affording a ready at taohmeut to the ears on the vessel body. Theguide 4, may be of any suitable or desirable construction, but I preferto use a piece of angle-iron having its upwardly projecting portioncurved or twisted to present a'flat surface against which the end of thewire strikes and affording no obstruction to the end of the wire whensubjected to the twisting action of the tool or plunger. This angleironmay be secured to the bed-plate 1, through its horizontal portion by thejam nut 22, and washer 23.

What I claim asnew, anddesire to secure by Letters Patent, is l l. Atool for forming the ends of wire bails for vessel handles, comprisingan upright mandrel and a plunger adapted to surround said mandrel havinga portion of its side cut away, the walls of said out being curved toimpart a screw action to the plunger, substantially as described.

2. Atool for forming the ends of wire bails for vessel handles,comprising an upright mandrel and a plunger adapted to surround saidmandrel, having a portion of its side cut away, one of the walls of saidout being spiral or screw shaped and the inner edge of said walldescribing a greater spiral or curve than the outer edge, substantiallyas described.

3. A tool for forming the ends of wire bails for vessel handles,comprising an upright mandrel and a plunger adapted to surround saidmandrel, havinga portion of its side cut away, one of the walls of saidout being spiral or screw-shaped, and the other wall being substantiallycam-shaped, substantially as described.

4. A tool for forming the ends of wire bails for vessel handlescomprising an upright mandrel and a plunger adapted to surround saidmandrel, having a portion of its side cut away, one of the walls of saidout being spiral or screw-shaped, and the inner edge of said walldescribing a greater spiral or curve than the outer edge, and anopposite wall substantially cam-shaped, substantially as described.

5. A tool for forming the ends of wire bails for vessel handlescomprising an upright mandrel, aplungeradapted to surround said mandrelhaving a portion of its side cut away, one of the walls of said outbeing spiral or screw-shaped and the inner edge of said wall describinga greater spiral or curve than the outer edge, and an oppositecam-shaped wall provided on its inner edge with a bend, are or chamfer,substantially as described.

6. A hollow plunger having a portion of its side cut away, one of thewalls of said out being spiral or screw-shaped and the opposite wallcam-shaped, said walls approaching each other at the top of the plungerand provided with the intermediate slot or recess, in combination with amandrel adapted to be surrounded by said plunger substantially asdescribed for the purposes set forth.

7. A tool for forming the ends of wire balls for vessel handles,co1nprisingan upright mandrel, aplunger adapted to surround said mandrelhaving a portion of its side cut away,

one of the walls of said out being spiral or screw-shaped and the inneredge of said wall describing a greater spiral or curve than the outeredge, and an opposite cam-shaped wall provided with a bend, are orchamfer on its inner edge, said walls approaching each other at the topof the plunger but separated at that point by an integral ring-shapedportion provided with a slot or recess, substantially as described.

8. A tool for forming the ends of Wire bails for vessel handlescomprising a slotted wire guide, an upright mandrel in line withaportion of the slot in said guide and a screw acting plunger,substantially as described.

9. A tool for forming the ends of wire bails for vessel handlescomprising a slotted wire guide, the bottom of said slot and one sidethereof being prolonged to an upright mandrel, in combination with ascrew acting pl unger, substantially as described.

10. A tool for forming the ends of wire bails for vessel handles,comprising a slotted wire guide, the bottom of said slot and one sidethereof being prolonged to an upright mandrel, in combination with aplunger adapted to surround said mandrel and having a portion of itsside cut away, one of the walls of said cut being spiral orscrew-shaped, and the inner edge of said Wall describing a greaterspiral or curve than the outer edge, and an opposite cam-shaped wallprovided with a bend, are or chamter on its inner edge, said wallsapproaching each other at the top of the plunger, but separated at thatpoint by an integral ring-shaped portion provided with a slot or recess,and a gage to limit the insertion of the wire, all combined and arrangedto operate, substantially as described.
